A Morning Line of Stars and Planets

Explanation: Early morning dog walkers got a visual treat last week as bright stars and planets appeared to line up. Pictured above, easily visible from left to right, were the Pleiades open star cluster, Jupiter , Venus , and the “ Follower ” star Aldebaran , all seen before a starry background. The image was taken from the Atacama desert in western South America . The glow of the rising Sun can be seen over the eastern horizon. Jupiter and Venus will continue to dazzle pre-dawn strollers all over planet Earth for the rest of the month, although even now the morning planets are seen projected away from the line connecting their distant stellar sky mates .
